中文摘要：

为有效减少冗余数据传输,增强安全性,提出了一种基于单向函数的传感器网络安全数据汇聚方案,汇聚节点无须解密数据,利用单向函数完成数据完整性检查、身份认证、数据汇聚等,保证了端到端传输的数据私密性。与相关数据汇聚方案相比,除了具有较小的能耗开销,该方案还在抵抗主动攻击、节点妥协攻击及DoS攻击等恶意行为方面具有较高的安全性。

英文摘要：

For reducing redundant transmissions and enhancing security, this paper proposed a secure data aggregating method for wireless sensor networks based on one-way function. The aggregators completed the data integrity checking, source identity authentication and data aggregation without decrypting the cipher-text and ensured the data privacy for end-to-end transmission. Compared with related scheme, besides lower energy consumption, the proposed scheme has higher security in terms of resilient against active attack, node compromise attack and DoS attack.
